In 1983 a big space next to the Auditorium was urbanized: it is the called Joan Sebastian Bach Square, with a Josep M. Subirachs sculpture. This sculpture, in honor of Pau Casals, represents Apolo, God of music and poetry, playing cello. On the base of the sculpture you can read the following phrase: "Bach is a miracle".
The architect Jordi Boent i Armengol was the person who designed the plaque and explains:
"We thought making the most of the space as a resting and leisure place, and also, using the side wall of the Auditorium, as a place in open air for musical events or not, as long as they raise the spirits".
